IMPROVEMENT IN HAY-LOADERS.

The Schedule referred to in these Letters Patent and making parl: of the same To all whom it may concern.:

Be it known that I, DAVID CLAGETT, of Hagerstown, in the county of' Washington and `State of Maryland, have invented a certain Improvement in Hay-Loaders; and I do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the annexed drawing making part of this specification, in whicli Figure 1 is a plan view of my improved hayloader.

Figure 2 is a vertical longitudinal section of the same.

Figures 3 is a similar section, showing a detached port-ion of the iriacliiiie only.

The same letters are used in all the figures in the designation of identical part-s.

This invention relates to hay-loaders of that class which is attached to the rear end of a wagon, and takesup the hay from the ground, and elcvates it by means of endless belts or chains provided at intervals with rakes.

My improvements consist in the combination and arrangement of certain devices, constituting a part of the loader, which will be more specifically pointed out in the subjoined description and claim.

To enable those skilled iii the art to make and use my invention, I will proceed to describe its const-rua, tion and operation.

The frame ot' the loader, consisting, mainly, of two long paiallel beams, A A, united by cross-beams, is mounted, at the rear end, by axles B, upon carryingwheels C, in the manner shown, the wheels revolving loosely upon their axles.

An inclined Ltrough, D, is hung upon the axles, between the wheels. lts ends are open, the lower one resting upon the. ground, while the upper one rises to any required heightabove the axles, and is provided with an extension, Dl, arranged` at about right angles to the main body, as clearly 'shown -iu` iff. 2.

The hay is elevated over tlie'bottom, D2, of the trough anddelivered upon the bottom, D, of its extension, by means of rakes, E2, whicliare arranged, Aat suitable intervals, on endless chains or belts, E El. These c liains are arranged upon rollers, F and l0', 'the latter of which has its hearings in the sides ot' the lupper end of the trough D, while the former is placed near the lower end, in such ina-nner that the teeth of the rakes in passing under it may just come in contact with the ground.

Where chains are used, the roller F', to which the power is applied, is provided with sprockets, to engage with the links oi' the chains, in the manner shown.

The journals of the roller F extend soine distance beyond their bearings, and one of them is, in the example shown, provided with a spur-wheel, G1, which gears with, and is driven by, a large spurwheel, G, fastened to the inner face of one of the carrying-wheels, so as to revolve said roller in the direction indicated by the arrow.

In a full-sized machine, where the roller F will be a considerable distance above the carrying-wheels, so as to make iinpracticable to use gear-wheels, and give to it the necessary velocity, I shall substitute pulleys and a belt for such wheels.

A ratchet-wheel, G2, is fastened to the carryingwheel, from which the roller F' is driven, and engaged by a pawl, G, which is arranged on the frame, so as to prevent the rotation of such carryiugwlieel in the event of backing the machine.

That journal of the roller F which carries the driving-wheel G1 is guided in its oscillations with the trough, caused by passing over uneveuiiess of the ground, in a sectoral groove, A, which is `concentric with the axle B, and formed in a standard or supplei'ucntary frame, A1, erected upon the main frame, as clearly .shown 'in 3. By this means the true distance between the centers of the roller and carryingf wheel is insured, which is essential to a proper operation of the machine.

H represents an after-rake, hung, by journals on its head, h, in the. sides of the trough D, above thc eiulless-chain i'akes. Its teeth, lwhich may be made of the form shown, are curi-'ed d wn in rear of thel roller F to the ground, with which they are held in firm contact' by means of a cross-bar, H', caused to press upon them by springs, h' h', by which it is aitaclied to the trough, in the manner sliowi'i. This after-rake will take along any hay which may not be. reached by the chain-iu kes by reason of unevenness oi' the ground, or the jolting inot-ion of the trough.

The hay elevated'to the extension of the trough is discharged atftlie rear end thereof by means of va series of rakes, K, hung upon and operated byacranked shaft, I, which receives a rota-ry motion, in the direcrection of the arrows, from the pulley 12,(liung upon the journal of the roller F', through a belt passing around said pulley and a pulley, 1, fastened to such crank-shaft.

In operating this loader, it is, by nieansof its beams A A, att-ached to the rear axle of the wagon to be loaded, in such manner that the extension of its inclined trough overliangs the body of suoli wagon.

Vliat I claim as my invention, and desire to se-v cure by Letters Patent, is-

l. The arrangement of the 'rakes K, operated by the crank-shaft l, iu relation to the elevating-lakes E2, as shown and described.

2. The combination, with the above-described parts, of the inclined trough D, arranged to operate as shown and described.

Iii tesiiinouy whereof I have signed my naine to this .specification in the presence of two subscribing witnesses this 14th dayof July, 1870.
